Struct mruby::eval::EvalContext

pub struct EvalContext {
    pub filename: String,
}

EvalContext is used to manipulate the state of a wrapped sys::mrb_state. Mrb maintains a stack of EvalContexts and MrbEval::eval uses the current context to set the __FILE__ magic constant on the sys::mrbc_context.

Fields

filename: String

Value of the __FILE__ magic constant that also appears in stack frames.

Methods

impl EvalContext

pub fn new<T>(filename: T) -> Self where
    T: AsRef<str>, 

Create a new EvalContext.

pub fn root() -> Self

Create a root, or default, EvalContext. The root context sets the __FILE__ magic constant to "(eval)".
